Abstract
A Coriolis mass flowmeter of a type in which a fluid to be measured is caused to flow in series by forming two parallel flow tubes and which are obtained by bending one conduit. The inlet portion of conduit between an external connecting portion connected to inlet piping and the inlet of one flow tube is bent in the shape of the letter L and bent in another direction in combination, and the outlet portion of conduit between an external connecting portion connected to outlet piping and the outlet of the other flow tube is bent in the shape of the letter L symmetrically with respect to the above inlet portion of conduit and bent in another direction in combination. The external connecting portions and are arranged on the same axis. The present invention simplifies the construction of connection to external piping, simplifies the assembling of the Coriolis mass flowmeter itself, and permits a high-accuracy measurement of mass flow rate by reducing the vibrations of external piping, etc.
